Kingdom of Soissons

The Kingdom/Domain of Soissons (461-486) was a rump state of the Western Roman Empire that lasted for 25 years. Soissons was led by Gallic-Roman warlord Aegidius under the rule of Majorian from 457 to 461, when Majorian died and Soissons effectively became independent under the rule of Aegidius and his son Syagrius.

History
As the Western Roman Empire fell, Emperor Majorian appointed Aegidius as magister militum of Roman Gaul in 457, but after he was killed by Ricimer in 461, Soissons became an independent domain of Aegidius and his family. Soissons was a Christian and pagan rump state that fought the Franks to the east and the Visigoths to the south, and Aegidius was friendly with the Romano-British of Cynan Meiriadog of Brittany in Brittany. When he died, he was succeeded by Syagrius, his son. The kingdom ended with the 486 battle of Soissons, where Clovis I of the Franks defeated Syagrius and forced him to submit to his rule. It became Neustria, a part of the new Frankish kingdom that was divided for the sake of Clovis's succession.
